The iRobot Roomba 860 is one of the more high-end robot vacuums out there. And right now, it's marked down from $699 to just $399. That's the lowest price the Roomba 860 has ever been. So what makes the Roomba 860 so great? Well, it uses AeroForce 3-Stage Performance Cleaning System to clean your home, so that it doesn't miss any dirt while cleaning. It does also use iAdapt Responsive Navigation Technology, which means it will navigate through your home without missing any spots, and also keep from running into objects like walls, tables and such. It does have infrared sensors that help it detect what is in front of it, and avoid obstacles. Additionally, there is a Lithium Ion battery inside, which allows you to let the Roomba 860 run for about 2-3 hours before needing a recharge. It is also self-charging so it'll automatically return to its charging base.
Robot vacuums are still a fairly new phenomenon, but the iRobot has really stolen the show with their Roomba lineup. Not only are they some of the best robot vacuums available, but they also have different models hitting different price points. Being able to grab the Roomba 860 for under $400 is an absolute steal, and it'll make a great gift this holiday season.Buy the iRobot Roomba 860
